Geotechnical study in Escacena del Campo

In Escacena del Campo, soils formed by limestones, dolomites and marbles predominate, accounting for more than half of the materials in the subsoil. These lithologies generally offer excellent bearing capacity, which favours the construction of direct shallow foundations, such as isolated footings or rafts. Likewise, the frequent presence of slates and schists constitutes a secondary base which, despite its limited permeability, provides adequate support for buildings, although it may require specific characterisation where fractured layers or layers showing significant alteration are located.

The seismic activity recorded in the area of Escacena del Campo is very low, with only two events in thirty years and a maximum magnitude of 2.3, so seismic risk does not significantly influence the design of structures. Since the substrate is not clayey, any risk linked to expansiveness is ruled out. In short, the main point to be assessed in a geotechnical study for the municipality will be the localised characterisation of the fracturing or alteration of the slates and schists, ensuring the suitability of the ground as support for the foundations proposed.
